The invention discloses a CC signal processing system, which belongs to the technical field of electric automobiles. The power supply end of a control module and the first end of a wake-up circuit are connected with a power supply; the wake-up end of the control module is connected with the second end of the wake-up circuit; the first control end of the control module is connected with the control end of a clamping circuit; the output end of the control module is connected with the input end of the clamping circuit and the power supply end of a CC signal detection circuit. The output end of the control module outputs a voltage signal with a first preset voltage value. The detection end of the control module is connected with the output end of the CC signal detection circuit; the third end of the wake-up circuit, the output end of the clamping circuit and the first input end of the CC signal detection circuit are all connected with a first access point of the charging interface, and the fourth end of the wake-up circuit and the second input end of the CC signal detection circuit are connected with a second access point of the charging interface. Whether an electric energy output interface is connected with the charging interface can be reliably judged.
